Djokovic drawn to face Zverev and Cilic in London

Novak Djokovic will face Alexander Zverev and Marin Cilic in the round-robin stage at the ATP Finals, while Roger Federer will get the chance to exact revenge on Kevin Anderson in London.

Five-time champion Djokovic was drawn in Group Guga Kuerten on the day he returned to the top of the rankings and Rafael Nadal withdrew from the season-ending tournament due to ankle and abdominal injuries.

The 14-time grand slam champion, guaranteed to end the year as world number one, will compete with Zverev, Cilic and debutant Josh Isner - Nadal's replacement - for a place in the semi-finals.

Djokovic's 22-match unbeaten run was ended by Karen Khachanov in the Paris Masters final on Sunday after beating Federer in a classic last-four encounter.
